The problem to be solved in this project is to devise and test an improved method for measuring source and detector positions in an RTT system. The RTT is a fixed gantry x-ray computed tomography scanner. The current method for geometry calibration has certain limitations, principally that it can only derive variations in the XY plane (Z direction is the direction of travel through the machine) and the test object needs to be scanned multiple times.

The idea is for the student to design a test piece that when scanned and analysed allows for accurate source and detector position estimates, and then to prove that the approach works by simulation.
